Wright iron ore mine in Canada. In 2011, we delivered 5,760 spiral starts and in 2012 we delivered an additional 2,688 iron ore spiral starts to the mine. These represented the largest delivery of iron ore spirals to any one mine site. To meet Mont Wright's specific beneficiation requirements, we embarked on an extensive research

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
